COMPOSITION-APPLYING DEVICE FOR BOOK-MATCH MACHINES. I

Application and February 4, 1922. Serial No. 584,258.

To all whom it may concern:

Be it known that I, WILLIAM H. SHor'rEn,

a citizenof the United States, and resi cut of Barberton, in the countyof Summit State of Ohio, have inven'ted certain ne and usefulImprovements in Composition- Applying Devices for Book-Match Machines,of which the following is 'a specifi-.

cation. 1

This invention relates to means for applying match-ignition material tomatch-book covers and the like; having reference, more especially, to animprovement in composition applying devices of the general characterdescribed in Letters Patent of the United States'No. 1,042,472, datedOctober 29, 1912.

The machine set out in said patent includes a carrier wherebyspaced-apart match books are advanced in close relation to the peripheryof a rotating wheel by means of which ignition paint is transferred froma tank to the fastened cover folds of the match books. In the practicaloperation of the machine a doctor" or auge plate associated with thewheel regu ates the quantity of-material carried up from the contents ofthe tank by the wheel and applied to the covers. "'The composition atthe edges of the tank becomes hard, and fragments of the hardmaterialisometimes break OE and lodge between .the gauge plate and thewheel; thereby preventing the proper transference of the composition tothe match books. This results in the production of a number of imperfectbooks before the attendant observes the defect. Sometimes a similartrouble is caused by a broken splint which enters the composition andworks around in the tank until the splint becomes lcidged between thewheel and the gauge p ate.

The object of my invention is to overcome the difliculties abovementioned, and to that end I provide the composition applyingwheel withperipheral projections which cooperate with the gauge plate to preventthe lodgment of foreign matter between the wheel and the plate, as willbe hereinafter described and olaimed.-

OHIO,- ASSIGNOR To run DIAMOND MATCH 2 is a plan of the said mechanismath of travel of the match covers (as b) "(with the end folds of thecovers projecting beyond the carrier) are assembled and bound'togetherin book form; thence transported to and past a structure wherebyfrictional ignition substance of the consistency of-paint is appliedexteriorly to the under surfaces of the projecting end folds of thecovers, and thence carried through an extended drying path.

The paint-applying structure, in the articular form shown, comprises astandar 11 provided with posts 12, 13 having suitable bracket arms 14sup orting a track section 15 for the carrier. 8

adapted to contain the ignition composition. Mounted to rotate withinthe tank is a wheel 17 the periphery of which is adapted to carry up thecomposition into the path of the ro ecting folds of the covers, and thusappfj the composition to the latter durin their travel. This wheel isfast on a sha 18 having its bearing in the 0st 13 on the standard andbein provide with a spur wheel 19 in mesh w1th a, pinion 20 on a shaft21 which has its bearing in a bracket 22 on the standard. The pinionmeshes with a suitably-disposed spur wheel 23 fast on a shaft 24 whichhas its bearings in the post 12 and is provided with a gear wheel 25 inn the standard is also, supported, beneath the carrier, a tank 16,

mesh with rack teeth 26 on the links of the the gears 19, 23 and theirrespective shafts are concurrently rotated in such a manner that thegear 23 advances the carrier 10 and the shaft 18 rotates the compositionapplyin wheel.

Cmbracing the rim of the wheel is the forked end of an angular gaugeplate 28, the active portion of which comprises an edge 29 which isappropriately spaced from the periphery of the wheel to determine thethickness of the film of composition carried up to the book covers bythe wheel. The plate is adjustably affixed to the adjacent bracket arm14, preferably by means of a set-screw 30 passing through a slot 31 inthe plate.

According to my invention the periphery of the wheel is provided with aseries of equally-spaced projections 32 which extend beyond theperiphery a distance equal to the depth of composition to be carried upand deposited on the covers. This is usually about of an inch. In thepresent instance four projections are provided. the same beingconstituted by hard metal inserts in the periphery of the wheel. Therotation of the wheel is so timed in relation to the travel of thecarrier that the book covers are acted upon by the peripheral surface ofthe wheel between the projections, such projections in their travelclearing the books.

By the construction above. described it will be seen that if any foreignmatter, such, for example, as fragments of hard composition or loosesplints, enter between the wheel and the gauge plate. the peripheralprojections will co-act with the gauge plate to break up such matter orwill carry the matter past the plate, thus insuring a uniformapplication of the composition to the book-covers.

It is to be understood that my invention is not limited to the specific.construction herein disclosed, as the same may be modilied within theprinciple of my invention and the scope of the appended claims.

I claim- 1. The combination with a'carrier for a succession of separatedarticles, of a container tor ignition material, a wheel mount; ed torotate in said container and to trans fer the material therefrom to thesurlace of said articles, said wheel having spaced-apart peripheralprojections, a gauge plate adjacent the periphery ot the wheel and thepath of rotation of said projections, and means for rotating said wheelin synchronisni with the travel of the aiticles whereby the pe ripheralportions of the wheel between the projections apply the material to thearticles and the projections escape the articles.

2. The combination with a carrier tor a succession of separatedmatch-lmoks. of a container for ignition material. a \vlteel mounted torotate in said container and to transfer the material therefrom to thesaid books, said wheel having in its periphery a series of regularlyspaced projecting insorts. a gauge plate adjacent the periphery of thewheel and the path of the projecting ends ol the inserts. and means forrotating said wheel in synchronism with the travel of the books wherebythe peripheral portions of the wheel between the inserts apply thematerial to the match-books and whereliv the projecting ends of theinserts escape the books.

3. ln means vfor applying match ignition composition to book-matches, atank, a composition applying wheel therein having peripheralprojections. and a plate having a forked end embracing the periphery ofthe wheel. said end having an edge portion spaced from the wheel toconstitute a gauge to determine the thickness of the material which iscarried up by the periphery of the wheel, said edge portion co-operatingWith the said projections to break up fragments of hard substances.
